support for asynchronous processing of SIP responses in configuration file

new operating mode for usrloc – dbreadonly – read records at startup, but don’t update them in database at runtime – can be done by a dedicated SIP server that receives replicated registration traffic, improving the speed of SIP routing servers

execution of an event route for traffic that generates initial parsing errors – good for automatically blocking the source IP

plugin-like support for kamctl to be extended with new commands

detailed list of additions is very long, duplicating the content here making no sense, therefore head to read the dedicated wiki page:

Project achievements during v4.1.0 development cycle

the project organized its first dedicated event, Kamailio World, with participants from 5 continents and selected group of speakers, resulting in a tremendous success. The second edition has been announced for April 2-4, 2014, in Berlin, Germany

development team had a significant growth, four of the new modules in this version were contributed by new developers and few other long standing contributors became official developers

Packages will be uploaded as soon as they are built by developers (Debian and Ubuntu debs as well as RPMs for Centos, RedHat, Fedora and OpenSUSE) or submitted by community for other operating systems.

Many thanks to those contributing with code, helping testing or advocating the project!We are looking forward to meeting many of you at next Kamailio World Conference!

Note: Kamailio is the new name of OpenSER project, name changed on July 28, 2008, due to trademark issues. First version under Kamailio name was 1.4.0. Older versions continued to use OpenSER name. Project site and SVN repository on SourceForge.net still use the old name OpenSER. Source code since release 3.0.0 (when the merge of source code trees of Kamailio and SER was completed) is hosted on GIT repository at http://sip-router.org. Starting with version 4.0.0, SER has been absorbed in Kamailio flavour, which became the default distribution of the project.

Short History

The initial name of the project was SIP Express Router (aka SER), started in 2001 by Fraunhofer Fokus Research Institute and released under GPLv2 in 2002. In 2005, OpenSER project spawned from SER and had to change the name to Kamailio in summer of 2008 due to trademark claims. During the autumn of 2008, Kamailio and SER teams decided to join back the projects and use further the Kamailio name.
